Best Folate Supplements of 2026

Not everyone is shopping for the standard dose. If a clinician has told you to take 1 mg of folic acid daily — a common instruction after a low blood result, or alongside certain prescriptions — most bottles here can't get you there without doubling up. This one does it in a single vegetarian tablet, and that is precisely the job we keep it for.

For a 1,000 mcg dose (1,667 mcg DFE) the tablet stays small, and the formula is stripped down: no sugar, yeast, soy, wheat, egg, artificial colors, artificial flavors, or preservatives. It's manufactured in a GMP-compliant U.S. facility, a detail worth more than the word premium on a label. Two hundred and forty tablets is about eight months at one a day, so you're not reordering every few weeks.

The limitation is the strength itself. There's no 400 mcg option in this bottle and nothing to split, so it's a poor starting point if you haven't settled on a dose — begin with the Nature Made bottle and move here when the number changes. Once it has, this is the least fussy way to take 1 mg we've found in this group.

If a folic acid supplement has never done anything you could notice, the form is usually the explanation. Folic acid is synthetic and has to be converted to 5-MTHF before your body can use it; methylfolate arrives already converted. Jarrow puts 400 mcg of that active form, Quatrefolic, into a capsule — a standard dose without the conversion step.

The capsule is the smallest thing in this guide, tasteless, and easy to take with or without food. Sixty of them is two months, shorter than most bottles here and the trade-off for a product this specific. It's also the cheapest way into methylfolate in this group, which matters when you're still finding out whether the form suits you.

We rate it highest as a first methylfolate purchase. The 15 mg bottles get all the attention, but 400 mcg is where most people should begin, and a couple of months is long enough to see how the methylated form sits with you before committing to a bigger bottle — or to Thorne's 1 mg if you already know it does.

Thorne runs four rounds of testing on every batch, from raw-material purity through to shelf life, and that is most of what the higher price buys. Plenty of methylfolate bottles say lab tested and leave it there; this is the one in our group that spells out what the testing consists of. On a supplement you take daily and can't otherwise verify, we think that's worth paying for.

The dose is 1 mg of active 5-MTHF — two and a half times the standard 400 mcg — in a capsule small enough to swallow without a second thought. It's the sensible step up for someone who has confirmed they don't convert folic acid well and wants more per day than Jarrow's 400 mcg.

The bottle holds 60 capsules, two months' worth, and it's the priciest route to 1 mg of methylfolate here. If all you want is active folate at that dose, NOW's 1,000 mcg tablets do the same job for a good deal less. Thorne is for the buyer who wants the testing record more than the bargain.

Set this bottle next to Thorne's and the differences are packaging and price rather than dose: both deliver 1,000 mcg of active methylfolate per serving, and NOW gives you 180 tablets instead of 60. If you've already decided active folate at 1 mg is right for you, we can't find a practical reason to spend more.

The tablets are small and tasteless, easy to take with or without food, and six months of doses in one bottle means fewer reorders and less chance of running out mid-week. Manufacturing carries NPA A-rated GMP certification, which is a real standard rather than a slogan, and the methylfolate is the Quatrefolic form.

The caveat belongs to the dose, not the product. A thousand micrograms of methylfolate is a substantial jump from 400 mcg, and at that level some people notice headaches, jitteriness, or trouble settling at night. If you've never taken the methylated form, spend a couple of months at 400 mcg first; the big bottle will still be here.

Fifteen milligrams is about 37 times the folate in a standard 400 mcg tablet, which puts this bottle in a different category from everything else on this page. This is the strength people arrive at after a genetic test or a specialist's protocol — not something to pick up because a bigger number sounds better.

What you get is 120 vegetarian capsules, four months at one a day, free of gluten, wheat, yeast, lactose, soy, artificial flavors, and preservatives, and non-GMO. Carlyle describes the product as laboratory tested and guaranteed, and the capsules go down easily.

Mood and energy are the reasons people end up at this dose, and they're also where the experience gets more variable: nausea, headaches, and a wired, overstimulated feeling turn up often enough to take seriously. That's a dosing question rather than a manufacturing one, and it's why no high-potency bottle is the place to start. Our take is that this is a clean, fairly priced version of a serious strength, and a poor first purchase — get established on 400 mcg or 1 mg, then come back if your clinician wants you higher.

Two ingredients share one capsule: 15 mg of L-methylfolate in the 5-MTHF calcium salt form, and methylcobalamin B12 as a cofactor. The pairing is the point. Folate and B12 are used together in methylation, and a high-dose folate product without B12 usually means a second bottle on the counter and a second pill at breakfast.

The capsules are easy to swallow with only a slight taste, and everything here is the active form — no folic acid, no conversion required. That's the version of this supplement we reach for when someone has been told their methylation pathway doesn't work properly.

The hesitation is the dose for anyone new to methylfolate. Fifteen milligrams is a lot to begin with, and nausea, headaches, and stomach upset are the complaints that come with this potency. Start at 400 mcg or 1 mg and step up on advice; the smaller bottles above are not a lesser product, they're the right on-ramp.

Where this one wins is among people already at a high dose and staying there. Ten of these capsules do the work of a folate pill plus a separate B12, the label is explicit about the salt form, and the price sits between the bargain and premium bottles here. That's a quiet advantage, and it's the reason we kept it in the guide.

This ships as two bottles of 180 tablets, 360 doses in total — roughly a year at one a day, and the longest supply in this guide. That format is the entire proposition: you buy folate once, the second bottle goes in a cupboard, and you stop thinking about reordering.

Each tablet lists 1,700 mcg DFE of 5-MTHF, the active form, which places it between the standard-dose products and the 15 mg bottles rather than at either end. The tablets are small and easy to swallow, and the formula is built on the methylated form with no folic acid to convert.

It's an odd middle child in that respect — more than a 400 mcg tablet, less than a high-potency capsule — and it makes the most sense for someone whose clinician has nudged them above the standard dose without going all the way to 15 mg. Life Extension's following among people with MTHFR variants is the other reason this bottle stays in the guide.

What gives us pause is the commitment. Three hundred and sixty tablets is a great deal of folate to buy before you know whether methylfolate agrees with you, and a two-bottle pack is a poor first purchase for exactly that reason. Establish the form on a smaller bottle, then come here for the year's worth.
